Many IETF working groups use external code repository services, primarily GitHub, in managing their work. Individual working groups, while continuing to operate within IETF guidelines for working group activity, have developed their own policies and practices for how they use these services. These policies and practices cover aspects such as: managing discussion between working group mailing lists and GitHub issues and pull requests; how text contributions are expected to be made; labeling and naming conventions; maintaining readable draft snapshots; using tooling and automation; informing participants about IETF policies; and others. The GitHub Integration and Tooling (GIT) working group will select a set of such practices and document policies that support those practices. The policies will each detail how work is conducted by working groups that opt to follow the work practice. The goal is to provide both process and tooling support for working groups that choose to adopt the practices. The documents produced by this group may apply to services similar to GitHub. However, documenting generalized policies that are designed to apply to multiple services or policies specific to services besides GitHub are out of scope for this working group. Pursuing such work requires a re-charter. The documents produced by this group will not alter the Internet Standards Process (BCP 9). They will describe how to work within it. Whether working groups choose to use GitHub or the documented policies to support their work will remain entirely at their discretion. The working group may also discuss tooling requirements in support of GitHub use. Decisions about implementing specific tooling needs will be undertaken by the IETF Tools Team in consultation with working group participants and other interested contributors.
